Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, unless otherwise stated, the use of the terms of orientation such as "axial" and "radial" in reference to the rotational axis of the respective component, generally "up" and "down" in reference to the normal installation of the fan drive mechanism provided by the present disclosure, and specifically with reference to the orientation of the drawing shown in fig. 4, "inner" and "outer" refer to the inner and outer contours of the respective component, and the use of the terms "first" and "second" in the present disclosure is intended to distinguish one element from another, and is not sequential or significant. Furthermore, in the following description, when referring to the drawings, the same reference numerals in different drawings denote the same or corresponding elements.
As shown in fig. 1 and 2, when the sanitation vehicle is designed, due to the influence of the impeller 11 of the fan, the volute 10, the air inlet chamber 5 and the like, the longitudinal size of the sanitation vehicle, i.e., the size in the front-rear direction of the vehicle, is large, so that the wheelbase of the whole vehicle is large, and the passing performance of the whole vehicle is influenced.
In addition, as for the fan driving mechanism, as shown in fig. 1 and 2, in the prior belt transmission scheme, a driving wheel 31 is connected to the power member 20, for example, an output shaft of a motor, through a coupling to serve as the driving wheel, a fan pulley 32 is coaxially connected to the impeller 11 of the fan to serve as a driven wheel, and the driving wheel 31 drives the driven wheel to rotate through a V-belt or a poly-V belt 33, thereby driving the impeller 11 of the fan to rotate to generate negative pressure. However, the existing belt transmission mode is quick in abrasion, the whole group of belts needs to be replaced regularly, the replacement difficulty of the belts is high, and time and labor are wasted; the belt pulley transmission needs to use a tension pulley, the tension force is adjusted periodically, and manpower is wasted; the transmission chain is longer, so that the transmission efficiency is influenced; the belt is easy to slip when starting; the belt transmission has high precision requirement during assembly, and the dislocation of the belt wheel groove can cause transmission failure.
As shown in fig. 3, in the prior art hydraulic transmission scheme, an impeller 11 is fixed on an output shaft of a hydraulic motor 4, and the hydraulic motor 4 drives the impeller 11 to rotate so as to generate negative pressure. However, in the conventional hydraulic transmission, when the rotation balance of the impeller 11 is damaged by dust fall and foreign matters, the output shaft of the hydraulic motor is subjected to an alternating radial force generated by the impeller rotating at a high speed, and the long-time operation of the hydraulic motor causes damage to components; the transmission distance of the hydraulic system is long, and the efficiency of the hydraulic motor is low; the movement accuracy of the hydraulic motor is affected by hydraulic oil leakage and liquid compressibility, a strict transmission ratio and output rotating speed cannot be guaranteed, other parts are polluted by oil dirt due to the hydraulic oil leakage, and dust sucked by the rotation of the fan falls on the surfaces of the parts, so that the cleaning is difficult; in addition, the energy loss is large due to leakage loss, overflow loss, throttling loss, fluid friction loss and the like, and meanwhile, the temperature rise of the hydraulic oil is fast at a high rotating speed, so that an oil way sealing element is damaged in an accelerated mode, and the reliability of the system is reduced.
In view of the above problems, as shown in fig. 4 to 6, the present disclosure provides a fan driving mechanism, an impeller 11 of a fan is connected with an impeller shaft 12, and the fan driving mechanism is configured to drive the impeller shaft 12 to rotate, specifically, the fan driving mechanism provided by the present disclosure includes a power part 20 connected with the impeller shaft 12, and a first support 21 and a second support 22 that are sleeved on the impeller shaft 12 and located between a housing 13 of the fan and the power part 20, and the impeller shaft 12 rotatably passes through a lubrication cavity 23 formed by the first support 21 and the second support 22.
